CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation application of prior application Ser. No. 15/441,986, filed on Feb. 24, 2017, which has issued as U.S. Pat. No. 10,884,692 on Jan. 5, 2021, and is based on and claims priority under 35 U.S.C. § 119(a) of a Korean patent application filed on Mar. 2, 2016 in the Korean Intellectual Property Office and assigned Serial number 10-2016-0024977, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an electronic device. More particularly, the present disclosure relates to a technology that enables an electronic device to display an image and transmit the displayed image to an external device.

BACKGROUND

With advances in mobile communication and processor technologies, electronic devices such as mobile terminals and smartphones can support not only conventional call functions but also various advanced functions. Such an electronic device may be equipped with a display including a touch panel to output images generated by various functions. The electronic device may output images associated with various applications, web browsers, and video content on the display.

An electronic device may exchange various data with an external device through various wired or wireless communication schemes. In particular, the image displayed on the electronic device may also be displayed on the external device by use of a mirroring technology. The mirroring technology enables multiple electronic devices each having a display to share screen data. The image output on the display of an electronic device may be sent to an external device in peer-to-peer (P2P) mode through wireless local area communication like Wi-Fi, and the external device may display the received image at the same time as the electronic device. As such, the mirroring technology may be very effective for a user who wishes to view images that are created by an electronic device with a small display by use of an external device with a large display.

However, the existing mirroring technology, which transmits the image output on the display of the electronic device to the external device as it is, may not be suitable for achieving multitasking. For example, while the user is viewing video content using the external device, when a popup window for a social networking service (SNS) message is output on the electronic device, the popup window may also be output on the display of the external device. Output of the popup window on the external device would not be in accord with the intent of the user wishing to view video content on a larger screen.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

An expression “comprising” or “may comprise” used in the present disclosure indicates presence of a corresponding function, operation, or element and does not limit additional at least one function, operation, or element. Further, in the present disclosure, a term “comprise” or “have” indicates presence of a characteristic, numeral, operation, element, component, or combination thereof described in a specification and does not exclude presence or addition of at least one other characteristic, numeral, operation, element, component, or combination thereof.

In the present disclosure, an expression “or” includes any combination or the entire combination of together listed words. For example, “A or B” may include A, B, or A and B.

An expression of a first and a second in the present disclosure may represent various elements of the present disclosure, but do not limit corresponding elements. For example, the expression does not limit order and/or importance of corresponding elements. The expression may be used for distinguishing one element from another element. For example, both a first user device and a second user device are user devices and represent different user devices. For example, a first constituent element may be referred to as a second constituent element without deviating from the scope of the present disclosure, and similarly, a second constituent element may be referred to as a first constituent element.

When it is described that an element is “coupled” to another element, the element may be “directly coupled” to the other element or “electrically coupled” to the other element through a third element. However, when it is described that an element is “directly coupled” to another element, no element may exist between the element and the other element.

Terms used in the present disclosure are not to limit the present disclosure but to illustrate various embodiments. When using in a description of the present disclosure and the appended claims, a singular form includes a plurality of forms unless it is explicitly differently represented.

Unless differently defined, entire terms including a technical term and a scientific term used here have the same meaning as a meaning that may be generally understood by a person of common skill in the art.

Hereinafter, a description is given of various embodiments of the present disclosure enabling multitasking during image sharing with reference to FIGS. 4 to 17.

In various embodiments, the electronic device may have at least two displays. In the electronic device, the displays may be physically and/or electrically separated from each other, and may be used to output different images or separate portions of the same image. In an embodiment of the present disclosure, the electronic device may have only one display and output different images on separate regions of the display.

An external device may be a device having a display and may have a type identical to or different from that of the electronic device. For ease of description, it is assumed that the electronic device is a mobile terminal having a small display and the external device is a TV having a large display. However, the present disclosure is not limited thereto or thereby. The external device supports wireless communication such as Wi-Fi, Bluetooth, near field communication (NFC), and global navigation satellite system (GNSS), and may receive image data for sharing from the electronic device through wireless communication and output the received image data on the display.

An access point refers to an equipment that enables a wireless device such as an electronic device to access a network. The communication circuit of the electronic device may send and receive data to and from the network through an access point. The electronic device may send and receive data to and from the external device in peer-to-peer (P2P) mode without using an access point (e.g. Wi-Fi direct).

FIGS. 4A to 4B illustrate configurations of the display of the electronic device according to various embodiments of the present disclosure. The electronic device has a housing, and may include a first display on a first portion of the housing and a second display separate from the first display on a second portion of the housing.

FIG. 4A illustrates an electronic device having multiple displays arranged respectively in foldable regions of the housing.

Referring to FIG. 4A, the electronic device 400 a (e.g. electronic device 101) may have multiple displays including at least a first display 420 a and a second display 430 a. As shown, the housing 410 a may include two separable sub housings, for example, a body housing 412 a and a cover housing 414 a. A hinge 450 a may be arranged between the body housing 412 a and the cover housing 414 a so as to foldably couple the body housing 412 a and the cover housing 414 a.

The first display 420 a may be formed in a region (e.g. front surface) of the body housing 412 a. The second display 430 a may be formed in a region of the cover housing 414 a capable of covering at least a portion (e.g. first display 420 a) of the body housing 412 a. In an embodiment of the present disclosure, the second display 430 a may include, for example, different transparent display areas or mirror display areas.

In some embodiments, the second display 430 a may include multiple display areas (e.g. display areas 432 a and 434 a). Among the multiple display areas, at least one first display area (e.g. display area 434 a) may have attributes (e.g., size, shape, brightness, color, saturation, sharpness, transmittance, gamma, resolution, contrast, viewing angle, color gamut, color temperature, grayscale linearity, and transparency) different from those of at least one second display area (e.g. display area 432 a); and the attributes (e.g., size, shape, brightness, color, saturation, sharpness, transmittance, gamma, resolution, contrast, viewing angle, color gamut, color temperature, grayscale linearity, and transparency) of at least one first display area (e.g. display area 434 a) may be adjusted independently of those of at least one second display area (e.g. display area 432 a). In an embodiment of the present disclosure, the display area 434 a may be one of a transparent display area and a mirror display area.

In some embodiments, the electronic device 400 a may further include a third display 440 a. The third display 440 a may be formed on the other portion of the cover housing 414 a of the electronic device 400 a. For example, in the case where the second display 430 a is formed on a portion of the top surface of the cover housing 414 a, the third display 440 a may be formed on another portion of the top surface of the cover housing 414 a, on a portion of the bottom surface of the cover housing 414 a, or on a portion of the top or bottom surface of the cover housing 414 a covering at least a portion of the side surface of the body housing 412 a. In an embodiment of the present disclosure, the third display 440 a may include, for example, different transparent display areas or mirror display areas.

In FIG. 4A, the body housing 412 a and the cover housing 414 a are fully unfolded. The body housing 412 a and the cover housing 414 a may be rotated around the axis of the hinge 450 a. For example, the cover housing 414 a may be rotated so that the top surface of the body housing 412 a including the first display 420 a is completely covered with the top surface of the cover housing 414 a including the second display 430 a. In FIG. 4A, the first display 420 a and the second display 430 a are arranged so that they face each other when the electronic device 400 a is folded. However, in another embodiment, at least one of the first display 420 a and the second display 430 a may be placed on the outer surface of the electronic device 400 a (e.g. on the opposite surface of the body housing 412 a or the cover housing 414 a). The first display 420 a and the second display 430 a may be of the same shape.

Referring to FIG. 4B, among the multiple displays of the electronic device, at least one display (e.g. second display 430 b) may be formed on the inner surface of the cover housing 414 b (e.g. on the surface of the cover housing 414 b in a direction facing the reverse side of the display of the body housing 412 b when the cover housing 414 b is closed). When the cover housing 414 b is closed so as to contact the rear surface of the body housing 412 b, the multiple displays may be arranged on both sides of the cover housing 414 b and the body housing 412 b. When the cover housing 414 b is fully closed, screen data of one display (e.g. second display 430 b) may be transferred to another display (e.g. fourth display 460 b). For example, when the cover housing 414 b is closed, at least a portion of screen data on the second display 430 b may be displayed on the fourth display 460 b formed on the reverse side of the second display 430 b in the cover housing 414 b.

In an embodiment of the present disclosure, the electronic device 400 b may be folded in the opposite direction. For example, when the electronic device 400 b is folded in the opposite direction, the second display 430 b and the first display 420 b may be placed respectively in the front face and the rear face of the electronic device 400 b.

In an embodiment of the present disclosure, among the multiple displays, the fourth display 460 b may be driven with less power in comparison to the other displays. The fourth display 460 b operating in low power mode may be configured to continuously display designated information (e.g. current time, battery status, electric field status, or various notification information regarding received messages or missed calls) unless a designated input (e.g. screen lock key) is received. The fourth display 460 b may be operated by the main processor (e.g. processor 120) of the electronic device 400 b. Alternatively, the electronic device 400 b may include a separate low-power processor (not shown) to drive the fourth display 460 b in low power mode. When the electronic device 400 b includes a low-power processor, the low-power processor may control the fourth display 460 b to display the designated information.

In an embodiment of the present disclosure, the electronic device 400 b may determine the display to be used for presenting designated information (e.g. current time, battery status, electric field status, or various notification information regarding received messages or missed calls) among the multiple displays according to the opening and closing of the cover housing 414 b. For example, when the cover housing 414 b is closed, the electronic device 400 b may output the designated information on the fourth display 460 b. When the cover housing 414 b is open, the electronic device 400 b may output the designated information on the second display 430 b or on the display formed in the body housing 412 b (e.g. first display 420 b).

FIG. 4C illustrates an electronic device having displays in the front and rear surfaces of the housing according to an embodiment of the present disclosure.

Referring to FIG. 4C, the first display 420 c may be formed on the front surface of the housing 410 c, and the second display 430 c may be formed on the rear surface thereof in the opposite direction. A home key, a front-facing camera, and the like may be further included in the front surface of the housing 410 c, and a rear-facing camera, a speaker, and the like may be further included in the rear surface of the housing 410 c. In an embodiment of the present disclosure, the front face of the housing 410 c or the electronic device 400 c may be the same as the rear face thereof.

FIG. 4D illustrates an electronic device having a flexible display according to an embodiment of the present disclosure.

Referring to FIG. 4D, the display of the electronic device 400 d may be bent in one direction or in both directions. Other hardware components of the electronic device 400 d including the housing may be bendable in the same manner as the display. When the display is bent at an angle greater than or equal to a threshold, the display may be divided into two display areas with respect to the axis of bending and one of the display areas may be defined as the first display 420 d and the other may be defined as the second display 430 d.

Each of the electronic devices 400 a, 400 b, 400 c, 400 d shown in FIGS. 4A, 4B, 4C, and 4D is described as having two displays. However, the arrangements of displays are not limited thereto. The electronic device may have three or more displays or the electronic device may have a single display that can be used as multiple displays. For instance, a single plastic organic light-emitting diode display (POLED) display may be bent or folded to provide two or more displays.

FIG. 5 is a block diagram of an electronic device 500 according to various embodiments of the present disclosure.

Referring to FIG. 5, the electronic device 500 may include a first display 510, a second display 520, a memory 530, a control circuit 540 (e.g. at least one processor), a communication circuit 550 (e.g. a transceiver), and an audio processing circuit 560 (e.g. audio processor). One or more of the listed components may be omitted or replaced without deviating from the subject matter of the present disclosure. The electronic device 500 may include one or more of the components of the electronic device 101 or 201 shown in FIG. 1 or 2.

The first display 510 and the second display 520 may each display images and may each be realized using a display technology based on liquid crystals (LC), light-emitting diodes (LED), organic light-emitting diodes (OLED), micro electro mechanical systems (MEMS), or electronic paper. The first display 510 and the second display 520 may each include one or more of the elements constituting the display 160 or 260 shown in FIG. 1 or 2.

The first display 510 may be placed on a first portion of the housing, and the second display 520 may be placed on a second portion of the housing in separation from the first display 510. Various arrangements of the first display 510 and the second display 520 in the electronic device 500 are described above in connection with FIGS. 4A, 4B, and 4C.

The communication circuit 550 is configured to send and receive data to and from an external device 10, and may include at least one of the components constituting the communication interface 170 of FIG. 1 or the communication module 220 of FIG. 2. The communication circuit 550 may communicate with the external device 10 and/or an access point 20 through wireless local area communication like Wi-Fi. The communication circuit 550 may have two or more antennas, which may be used to transmit and receive data through different frequency bands. The configuration of the communication circuit 550 is described in more detail later with reference to FIG. 8.

The memory 530 may include a volatile memory and a non-volatile memory known in the art without particular restrictions. The memory 530 may be electrically connected with the control circuit 540 and may store various instructions executable by the control circuit 540. The instructions may include arithmetic operations, logical operations, data movement operations, input/output operations, and control operations, which can be recognized by the control circuit 540.

The control circuit 540 is configured to perform control, communication, or data handling operations for the individual components of the electronic device 500, and may include at least one of the elements constituting the control circuit or at least one processor 120 of FIG. 1 or the application control circuit or application processor 210 of FIG. 2. The control circuit 540 may be electrically connected with the various components of the electronic device 500 including the first display 510, second display 520, memory 530, communication circuit 550, and audio processing circuit 560. Although there is no particular restriction on the operational and data handling functions implementable by the control circuit 540 in the electronic device 500, the following description focuses on transmission and control functions performed by the control circuit 540 for displaying images on the display and controlling the communication circuit 550 to transfer images to the external device 10. The operations of the control circuit 540 to be described below may be executed by loading instructions stored in the memory 530 as described above.

The audio processing circuit 560 is configured to process, amplify, and output audio signals. The audio processing circuit 560 may control output of an audio signal through a speaker of the electronic device 500 or through an earphone (or external speaker) wiredly or wirelessly connected to the electronic device 500.

The control circuit 540 may supply a first image to the first display 510 and supply a second image to the second display 520. The first display 510 and the second display 520 may display the first image and the second image, respectively. Here, the first image and the second image may be displayed at the same time. The first image from the control circuit 540 may be supplied to the first display 510 through a first interface, and the second image may be supplied to the second display 520 through a second interface along a path independent of the first image.

When the image sharing function is enabled, the control circuit 540 may supply the communication circuit 550 with data associated with one of the first image and the second image selected by the user. Here, the associated data may be image data corresponding to one of the first image and the second image. The communication circuit 550 may establish a communication channel of P2P mode with the communication circuit of the external device 10 when the image sharing function is initiated. At this time, the communication circuit 550 may receive identification information and display capability information of the external device 10.

The communication circuit 550 may send the external device 10 data associated with one of the first image and the second image under the control of the control circuit 540. In the following description, the data sent to the external device 10 through the communication circuit 550 is referred to as “sharing data”. Next, a description is given of operations involved in transmitting the first image displayed on the first display 510 to the external device 10 according to user selection.

For example, to share the first image displayed on the first display 510 with the external device 10 according to user selection, the control circuit 540 may send the first image to the first display 510 through the first interface and send the first image to the external device 10 through the communication circuit 550 at the same time. Hence, the first image may be output on the first display 510 and the display of the external device 10, and the second image may be output on the second display 520 in parallel with display of the first image. Here, the control circuit 540 may generate the sharing data from the first image data in consideration of attributes of the external device 10 such as screen size and orientation. For example, when the first display 510 is in portrait orientation and the display of the external device 10 is in landscape orientation, the control circuit 540 may generate the sharing data by changing the orientation of the first image from portrait to landscape according to the display attribute of the external device 10.

In the case where the first image and the second image are accompanied respectively by first audio data and second audio data, when the image sharing function is executed according to the related art technology, the first audio data and second audio data may be mixed together and the mixed audio data may be sent to the external device 10 or output by the electronic device 500. In the electronic device 500 of the present disclosure, when the image sharing function is initiated for the first image, the control circuit 540 may send the first audio data associated with the first image to the external device 10 through the communication circuit 550 and send the second audio data associated with the second image to the audio processing circuit 560. Hence, the first image and associated first audio data may be output by the external device 10 for sharing, and the second audio data associated with the second image to be output only by the electronic device 500 may be output through the speaker of the electronic device 500 or through an earphone (or external speaker) wiredly or wirelessly connected to the electronic device 500.

In an embodiment of the present disclosure, when the external device 10 does not have a speaker for audio output, the first audio data may be output through the speaker of the electronic device 500 and the second audio data may be output through an earphone or headset wiredly or wirelessly connected to the electronic device 500.

The electronic device 500 may support multitasking for all available functions when the image sharing function is initiated. For example, to output a popup window in response to a specific event (e.g. reception of a social networking service (SNS) message or reception of a push message), the control circuit 540 may display the popup window on the second display 520 as a higher layer above the second image not being shared. Likewise, upon reception of an incoming call, the control circuit 540 may display a call handling window on the second display 520. At this time, the first display 510 and the external device 10 may continue to display the first image.

To display a menu window for controlling the shared first image (e.g. playback interval change, size or resolution adjustment, or volume adjustment), the electronic device 500 may display the menu window on the second display 520 other than the first display 510. As such, the first image may be continuously displayed on the first display 510 and the external device 10 while the menu window is being displayed.

In an embodiment of the present disclosure, the menu window for controlling the first image may be displayed on the first display 510 together with the first image. In this case, the menu window may be displayed as a higher layer above the second image. Alternatively, the first image may be reduced in size and the menu window may be displayed in the corresponding region secured by size reduction. Although a menu or popup window is displayed on the first display 510, as only the sharing data is sent to the external device 10, the menu or popup window is not displayed on the display of the external device 10.

FIG. 6 illustrates components of the electronic device 600 for sharing images with an external device according to various embodiments of the present disclosure. Hereinafter, a description is given of data flows between the individual components and operations thereof when the image sharing function is initiated for the first image in response to detection of an input on the electronic device 600.

In an embodiment of the present disclosure, the electronic device 600 may include a control circuit 640 (e.g. at least one processor), a first touchscreen panel (TSP) integrated circuit (IC) 614, a second TSP IC 624, a first interface 612, a second interface 622, a first display 610, a second display 620, and a communication circuit 650 (e.g. a transceiver).

The TSP IC refers to an IC (or control circuit) for controlling a touchscreen combined with a display as a single entity. The first TSP IC 614 may sense a user touch input on the first display 610, and the second TSP IC 624 may sense a user touch input on the second display 620.

The electronic device 600 may have a dual display interface (DDI) structure. That is, the electronic device 600 includes a first interface 612 to supply images to the first display 610 and a second interface 622 to supply images to the second display 620, and the first interface 612 and the second interface 622 may be used to form independent paths. The control circuit 640 may output a first image and a second image to the first interface 612 and the second interface 622, respectively and independently.

When the image sharing function is initiated for the first image, the control circuit 640 may supply data associated with the first image (i.e. sharing data) to the communication circuit 650. In the communication circuit 650, the sharing data may be received from the control circuit 640 through the interface 651; the sharing data may be encoded by the encoding end 652; and the sharing data may be modulated, amplified, and wirelessly transmitted by the transport end 653 to the external device 10.

In an embodiment of the present disclosure, the external device 10 may include a communication circuit 11, a video output unit 12, and an audio output unit 13.

In the communication circuit 11 (e.g. a transceiver) of the external device 10, the transport end 11 c may wirelessly receive sharing data; the decoding end 11 b may decode the received sharing data; and the interface end 11 a may separate the decoded sharing data into video data and audio data and supply the video data and the audio data respectively to the video output unit 12 and the audio output unit 13.

FIG. 7 illustrates components of the electronic device 700 for audio processing according to various embodiments of the present disclosure.

When the image sharing function is initiated, the first image may be sent to the first display 710 and the second image may be sent to the second display 720. In the case where the first image and the second image are accompanied respectively by first audio data and second audio data, it may be preferable that the first audio data is output together with the shared first image in the external device.

To this end, the control circuit 740 (e.g. at least one processor) may send the first image and the first audio data to the external device through the communication circuit 750 (e.g. a transceiver) and send the second audio data to the audio processing circuit 760 (e.g. an audio processor). Hence, the first image and associated first audio data may be output by the external device for sharing, and the second audio data associated with the second image to be output only by the electronic device 700 may be output through the speaker or SPK 762 of the electronic device 700 or through an earphone or E.P. 764 (or external speaker) wiredly or wirelessly connected to the electronic device 700.

In an embodiment of the present disclosure, when the external device 10 does not have a speaker for audio output, the control circuit 740 may send both the first audio data and the second audio data to the audio processing circuit 760, and the audio processing circuit 760 may output the first audio data to the speaker 762 and output the second audio data to the earphone 764.

FIG. 8 illustrates details of the communication circuit 860 (e.g. a transceiver) of the electronic device according to various embodiments of the present disclosure.

The communication circuit 860 (e.g. a transceiver) may include multiple antennas, which may send and receive data using different frequency bands. For example, the communication circuit 860 may have two antennas, and the first antenna 862 may use a first frequency band (e.g. 5 GHz) to send and receive data and the second antenna 864 may use a second frequency band (e.g. 2.5 GHz) to send and receive data. The communication circuit 860 may be implemented as a single chip, and may have processing circuits to encode, encrypt, and amplify baseband signals destined respectively for the first antenna 862 and the second antenna 864.

In an embodiment of the present disclosure, according to whether the image sharing function is initiated, the communication circuit 860 may use the first antenna 862 and the second antenna 864 in the following way under the control of the control circuit 840 (e.g. at least one processor).

When the image sharing function is not initiated, the communication circuit 860 may use the two antennas for multiple-input multiple-output (MIMO) to perform data transmission and reception using a wider bandwidth.

When the image sharing function is initiated, one of the first antenna 862 and the second antenna 864 (e.g. first antenna 862) may be configured to communicate with the access point 20, and the other thereof (e.g. second antenna 864) may be configured to establish a communication channel with the communication circuit of the external device 10 for P2P mode communication. At this time, the identification information and display capability information of the external device 10 may be received through the second antenna 864.

For example, in the case where the electronic device simultaneously executes a video player and a web browser, for image sharing, network data requested by the web browser may be received from the access point 20 through the first antenna 862, and image data produced by the video player may be sent to the external device 10 through the second antenna 864.

FIGS. 9A and 9B are screen representations depicting entering image sharing mode according to various embodiments of the present disclosure.

In an embodiment of the present disclosure, when a specified input (e.g. gesture, touch, button press, or voice input) is detected on the first display 910 or second display 920 of the electronic device 900, the control circuit (e.g. at least one processor 120 of FIG. 1 or control circuit 540 of FIG. 5) may display a menu 930 for image sharing on the display where the input is detected. When the image sharing function is initiated through the menu 930, the control circuit may control the communication circuit (e.g. communication interface 170 of FIG. 1 or communication circuit 550 of FIG. 5) to data associated with one of the first image and the second image output on the display where the input is detected.

For example, when a specified input (e.g. long press on a screen region or gesture involving touch and movement) is detected on the first display 910, the electronic device 900 may output a preset menu 930 on the first display 910. The menu 930 may contain various icons and text strings mapped with different functions. When an input is detected on the second display 920, the electronic device 900 may output the menu 930 on the second display 920.

When an icon 932 mapped with the image sharing function is selected from the menu 930, the communication circuit of the electronic device 900 may establish a communication channel with an external device. For example, referring to FIG. 9B, the electronic device 900 may send data associated with the first image output on the first display 910 to the external device 10 through the communication circuit, and the external device 10 may display the first image on the display thereof on the basis of the received data. Here, the first image and the second image may still be output respectively on the first display 910 and the second display 920.

In an embodiment of the present disclosure, when a preset application is executed or preset content is played back, the electronic device 900 may, automatically without a separate input, output a first image on the first display 910 and send sharing data associated with the first image to the external device 10 at least partially in parallel with display of the first image.

In addition, the first audio data associated with the first image may be sent to the external device 10 and output by the external device 10, and the second audio data associated with the second image may be output through the speaker or earphone of the electronic device 900.

FIGS. 10A, 10B, and 10C illustrate operations for handling various events occurring while image sharing is in progress according to various embodiments of the present disclosure.

In the case of related art, when a popup window is displayed in response to occurrence of an event (e.g. SNS message, push message of an application, or system notification) while the image sharing function is being executed, the popup window is directly output not only on the display of the electronic device 1000 but also on the display of the external device 10.

In various embodiments, as shown in FIG. 10A, when an event occurs, the electronic device 1000 may output a popup window 1030 corresponding to the event on the second display 1020 as a higher layer above the second image not being shared. When a popup event occurs, the control circuit (e.g. at least one processor 120 of FIG. 1 or control circuit 540 of FIG. 5) may generate a layer for popup window 1030 and provide the layer to the second interface. At this time, the popup window is not displayed on the first display 1010 or on the display of the external device 10, but the first image can be continuously displayed thereon.

In various embodiments, as shown in FIG. 10B, when a call is received, the electronic device 1000 may display a call handling window 1040 on the second display 1020. At this time, the first image may still be output on the first display 1010 and the display of the external device 10. When the first image is generated by playback of video content, playback may be paused or the external device 10 may pause output of the first audio data.

In various embodiments, as shown in FIG. 10C, to display a menu 1050 for controlling the first image shared with the external device 10 (e.g. playback duration change, size or resolution adjustment, or volume adjustment), the menu 1050 may be output not on the first display 1010 but on the second display 1020. Hence, the first image is continuously displayed on the first display 1010 and the external device 10, and the user may control the first image by use of the menu 1050 output on the second display 1020.

FIG. 11 illustrate changes in the display size and orientation of the external device 10 according to various embodiments of the present disclosure.

The size and/or orientation of the images displayed respectively on the first display 1110 and the second display 1120 may be changed horizontally or vertically according to the orientation of the electronic device 1100. For example, when the first display 1110 of the electronic device 1100 is in portrait orientation, the first image may be displayed in a region 1132 of the first display 1110 and other information related to the first image may be displayed in the remaining region 1134 of the first display 1110.

In an embodiment of the present disclosure, when the electronic device 1100 shares a screen image with the external device 10, the size and/or orientation of the image output on the display 1110 or 1120 of the electronic device 1100 may be different from that of the image output on the display of the external device 10. For example, when the image sharing function is initiated for the external device 10 while the first image of portrait orientation is output on the first display 1110 of the electronic device 1100, the control circuit (e.g. control circuit or at least one processor 120 shown in FIG. 1) may send sharing data of landscape orientation to the external device 10 in consideration of configuration information (e.g. screen size and resolution) of the external device 10.

FIG. 12 illustrates shared image switching according to various embodiments of the present disclosure.

When a specified input (e.g. gesture or swipe) is detected on one of the first display 1210 and the second display 1220 while one of the first image and the second image is being shared between the electronic device 1200 and the external device 10, the communication circuit (e.g. communication circuit 550 of FIG. 5) of the electronic device 1200 may send data associated with the other of the first image and the second image to the external device 10.

Upon detection of a specified input (e.g. gesture of moving a finger from the upper end of the first display 1210 to the upper end of the second display 1220) while the first image is being shared, the control circuit may stop sending sharing data associated with the first image to the external device 10 and send sharing data associated with the second image to the external device 10.
